The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, OYRUs W. SALADEE, of Circlevllle, in the county of Pickaway, and in the State of Ohio, have inventeda new and improved Mode of Constructing Revolving Door-Bells and I do hereby declare that the. following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to the lettersof reference marked there- My invention consists in rigidly connecting the bell to the shaft, or bolt passing through the door, and into the knob, or handle on the outside, so that the bell shall revolve with the knob, or handle; also, in the peculiar arrangement'lof any desired number of hammers secured to a plate, `and fastened to the inside of the door, and through which plate the bolt, or shaft of the bell passes, and which latter is provided with a notched ilange-wheel, so arranged, that in revolving the bell by the knob, or handle outside the door, the hammers are acted upon so as to make them strike the bell Yall .at once, or in rptation, so that the sound will be as if struck but once, or in rotation, one hammer striking the b'ell immediately after the'other, until a number of alarms is given corresponding with the number 0f hammers used and in greatly simplifying the construction and adding to the eciency of that class 'of door'- bells which is secured to and operated upon the door.

i Figure l represents my complete bell A. q q show the bell in section,- cut'in two in the centre; 0n, B, B, and B2,.reprsent the full outline and proportion of the shaft to which the bell is secured; and C Gfis'aflange-wheel, 'rigidly fixed on the bell-shaft, and which is provided with the notches d d dd, which are made to come in contact with the steel wires F F F F, the latter being secured in the round plate e e e, as seen in iig. 4; and on the outer ends of the spring-wires are secured the hammers g g g g. The bell is secured to the inner end of the shaft by a square hole through its centre, and made to closely tit the square, a, of the shaft B, and is held in position by the nut m. The outer end of the shaft B Bl has a screw-thread, B2, cut thereon, as seen in g. l, to receive the set-screw tap j and the lmob, or handle K,K, and L.

Figure 2 is an outside view of the bell, as seen whe in positionon the door; v

. Figure '3 represents a front View of the knob, or handle L, in form of a star.

Figure 4 is a face view of the plate c c c, secured to.

the insideofI the door by the screws 1, 2, 3, 4, and which plate is provided with ribs 1) p p p, which are made to hold the steel spring-wires f f f f, on the outer ends of which are the hammers g g g g. The dotted line d, where it crosses the wires f, indicates the point where the notches d d al d of the flange-wheel come in contact. In casting the plate c and hammers g, the wires f are iirst suitably prepared and dropped into the core-print of the mould, and the plate and ham-4 mers are thus cast on the ends of the wires.

Figure 5 is a view of the flange-wheel O, showing the edge of the ange, and the shoulders, or notches as manyA spaces as there are hammers, asthe number may vary from one to six.) Thendet one of the spacemarks represent the position of the shoulder dl. Let the'next one. be set back of the next space-mark onesixteenth of an inch, di, and in like manner d3 and d4; and th-us, when these shoulders pass over the wires f, the hammers will fall from the shoulders, and strike the bell, one after another, in quick succession. If but one wire and hammer` are used, the iange of the wheel G may have as many shoulders and notches, d, as it will receive, with a proper space between, and thus, by a slight turn of the knob of the bell, the hammer'will be acted upon two or three times, and produce almost the same alarm as in the other case.

The arrangement of my door-bell being thus fully described, its application to the door is effected as follows First, determine the point on the door where the shaft of the bell is to pass through from the inside, and bore the hole.

Second, take the plate c c c, having the hammers attached, and screw it to the inside of the door, so that the hole-inthe plate shall register with the one bored through the door. v

Third, pass the end of the bell-shaft Bl Bz through the door, and, from the outside, put on the knob-plate t, in the usual way, after which, screw on the set-screw taj until the shoulder on the shaft comes in contact. withv the plate O; then follow by screwing firmly up 'against the set-screw tap y' the knob or handle K K L, which latter rests against the ordinary knob-plate t, as seen in iig. 1.

The bell is now in proper position on the door, for operation, and by .taking hold of the knob, or handle K K L, and givingt a slight' turn to the right, the

shoulders d of the flange-wheel O, by their pressing against the wires j', sprin'g them back until the shoulders d pass, when they react and strike the bell, as already shown and described.

Having thus fully described the nature and object of my invention,

What I claim as new, and des' Ae to secure byLet- I ters Patent, is

l. Securing the bell A to the shaft, or handle B, as

In testimony that I claim the above-described mode of constructing' revolving door-bells, I have hereunto signed my name, this 9th day of January, 1869.
